How Does PREVENAR 13® Work?

The vaccine works by helping the body make antibodies to 13 types of the bacteria Streptococcus pneumonia. Antibodies are used by the body to recognise potentially harmful bacteria so that they can be destroyed before they cause infections. The antibodies should therefore help protect you against infections caused by those bacteria. As with any vaccine, Prevenar 13® will not protect everyone who is vaccinated.
